摘要
应用构造转换带理论对苏北盆地高邮凹陷真武、吴堡断裂带进行了研究。研究表明,构造转换带不仅可以发育于伸展断裂系统,同时也可以发育于走滑断裂系统,在不同的构造体系中具有不同的控油机制;在伸展构造体系中传递断层一般表现为压扭性质,具有较好的封闭能力;在走滑构造体系中则往往表现为张性,封闭能力较差。认为许庄、陈堡地区分别发育不同性质的构造转换带,具有不同的控油机制,这一认识为该区的进一步勘探开发提供了理论依据。
The theory of structural transition section is used to study Zhenwu and Wubao fault zones in Gaoyou Depression of Subei Basin. The study shows that not only the extended tectonic systems are developed in the tectonic transition sections, also the transition sections are grown in the extended tectonic system, there are different oil control mechanisms in different tectonic systems. In the extended tectonic systems, it is generally a press-torsion property with better seal capacity. While in a strike-slip tectonic system, it is intensive with poor seal capacity. It is considered that different tectonic transition sections with different oil control mechanisms are developed in Xuzhuang and Chenbao Areas, by which a theoretical basis is provided for further exploration and development in the area.
